V i i The means shown for applying pressure to i the jawmeinber 21toprodi1'ceuthe clamping ,i 1 i actionzcomprise's arod'29 havingan external screw`=-thread at which lit'is threadedin an i 70 I between the legsiof the yoke member 12 and is guidinglyconfined thereon to be `moved opening 3-3 in the upper, cross bar, portion of the yoke 12, the upper end of this rod being provided with a handle-forming cross bar 31. r`he rod 29 immediately below its threaded portion is of reduced diameter as represented at 32, its lower extremitybeing of still further reduced diameter as represented at 33. The jaw member' 21 contains a transversely disposed opening 34 and a vertical opening communicating with the opening 34, the rod 29 extending at its reduced portion 33 into the opening 34 and at its reduced portion 32 loosely into the opening 35, the rod 29 being provided at its reduced portion 33 with a collar 3G rigidly held thereon by a pin 37 extending transversely through the collar and the portion 33 of the rod 29, the bottom surface of the surrounding portion of the collar 36 being rounded as represented whereby the lower end of the actuating element comprising the rod 29 and 'collar 36 is of general spherical Contour and presents a surface of relatively large area.

The pressure of the upper .jaw member against the pipe to be clamped is produced by the engagement of the pressure producing device described against the bottom wall of the opening 34 in the jaw iininbei.` As the jaw member 21 loosely fits the guide'23, in order thatthis aw member may conformingly fit the pipe to be clamped, and as the threaded rod 29 and collar 36` loosely fit within the jaw member 21, the latter may.

adjust itself to conformingly fit against the pipe, under the applied pressure, without danger of cramping and straining the parts of the device; the clampino' jaw 21 being lifted and. held in raised position, by the engagement of the collar 36 with the top wall of the opening 34 in the jaw member 21.

To adapt the opposed j aws of the device to effectually clamp pipes of widely difierent diameters and without danger ofcrushing or otherwise distorting them, I provide the jaw sections 8 and 24 with teeth as shown extending throughout the length of these sections. The teeth on the lower jaw and represented at 38 are divergingly disposed upwardly from the center of the jaw section 8 as shown in Figs. 1 and 4, with the teeth at opposite sides of the center tilted slightly inwardly.

The toot-hed portion of the jaw section 24 comprises a pair of teeth 39 located at opposite sides of the center of this jaw member and a pair of teeth 40 located between the teeth 39 and likewise at opposite sides of the center of the jaw section 24.

The teeth 40 are disposed in substantial vertical alinement with the lowermost ones of the teeth 38, and the teeth 39, the outer sides of which are represented at 41, extend to the ends of the jaw section 24,v and in the gripping of a pipe of relatively small diameter as represented in Fig. 4, extend into the Valleys between the second and third lowermost ones of the teeth 38 at each side of the center of the'jaw section 8 and thus in intermesh therewith, the engagement of the jaw section 24 withv a larger pipe, as for example as shown in Fig. 1, being at the teeth 39.

It will be understoodfrom the foregoing that by providing the teeth on the jaws as shown and described am enabled to effectually clamp a wide range of sizes of pipes from quite small to large pipes without ol jectionable lateral overlapping ortelescoping of one jaw relative to the other with concsequent disadvantage in clamping small pipes. ,Therebeing no such telescoping action of the jaws in my device, the teeth on the jaws being directly opposed'to each'other, danger of crushing the pipes'is reduced to the minimum. i

lVhile I have illustrated and described a particular construction embodying my inven-,

tion, do not wish. to be understood as intending to limit it'thereto as the same may be variously modified `and altered without departing from the spirit of my nvention.

l/Vhat I claim as new, and desire to secure by Letters Patent, is:

1. In i a vise, the combination of teethequipped, directly opposed, 'jaws relatively movable toward and away fromeach other, the teeth on one of said jaws being arranged in series which diverge upwardly toward the other of said j aws, and certain of the teeth on the other of said jaws being so shaped as to extend into the valleys between certain of adjacent teeth o n said. first-named jaw in one position of the jaws.

- 2. In a vise, the combination of teethequipped, directly opposed, jaws relatively movable toward and away from each other, the teeth on one of said jaws being arranged in series which diverge upwardly toward the other of said jaws, the crests of certain of the teeth on the other of said j aws substantially directly opposing the crests of the lowermost teeth on said first-named jaw and others thereof being located beyond and extending below the adj acentteeth on this jaw and eX- tending into the space between said series of diverging teeth and opposing valleys formed between certain of the latter.

3. In a vise, the combination of teethequipped, directly opposed, jaws relatively movable toward and away from each other, the teeth on one of said aws being arranged in series which diverge upwardly toward the other of said jaws, the crests of certain of the teeth on lthe other of said aws substantia-lly directly opposing the crests of the lowermost teeth on said first-referred-to aw and others thereof'being 'located beyond and extending below the adjacent teeth on this aw and eX- tending into the space between said series of diverging teeth an'd extending into the valleys between certain of the teeth of said diverging series. f

4. In a `vise, the combination of directly opposed jaws relatively movable toward and away from each other and eachV provided with a plurality of teeth at opposite sides of I its center, the teethon said jaws being'arranged in oppositely diverging series, certain of the teeth on one of saidfjaw other than -the innerrnost teeth thereof being soshaped as to extend into the valleys between certain i io of adj acent teeth of the other of said jaws. i

5, Ina vise, the combination of directly opposed jaws relatively movable towardand away from each other andeach provided i withwa plurality of teethat opposite sides of i it center,tthe,teeth on one jawbeing` of greater number than the teethV on the other of said jaws andextendinglaterally beyond i the latter, the teethzon said jaws being a.r` f' ranged in oppositely diverging series, certain of'the teeth on oneof saidjawsfother than the innermost'teeth thereof being so shaped as to i extend intofthe Valleys between certain of adjaoent teeth on thebother of said jaws. a

i 6. In a Vise, thecombination of directly opposed jaws relatively'movable toward and` away from each other and each Vprovided with a plurality of teethat opposite Sides of its center, the teeth on one jaw being of greater numberthan the teeth on the other of said jaws and extending laterally beyond the latter, the teeth on'said jaws'being' ar-` ranged inoppositely diverging series, certain`v of the teeth on the one of said jaws provided i withl the lesser number of teeth, other than w the innermostteeth thereof, being so sh'aped i y as to extendninto the Valleys between certain i i of adj acent teeth on the other of saidijaws.
